Probably the best solution to listening to this symphony - unless the missing pages of the finale turn up, and let's hope they do - is the one proposed by Nicolaus Harnoncourt on his RCA set. Have a "workshop" at the beginning of the concert: an illustrated talk showing just how much we have left of Bruckner's music. Then proceed with the "normal" 3 movement performance. Even in the dark old days when nothing was generally known about the torso of the finale and the first three movements only were played, the incomplete conception was - and is - very moving indeed. Another alternative is to have a gap between the first three movements and any realisation of the finale. The wonders of the Adagio deserve a good pause for assimilation in any case!
The first three movements are played here very well indeed with an authentic "Bruckner sound" and though neither orchestra nor conductor are well known, nobody should be put off from buying the disc on that account. The performance of the finale actually makes the most cogent sense of the "Italian Committee's" realisation that I have heard - better than Inbal for example. Carrigan's completion on Chandos is fair enough until the horribly coarse coda with the Sousa trumpet but the disc has the advantage of recording of the actual fragments discovered up to the time of recording, so you have a chance to hear what is Bruckner and what is editor.
It is worth getting this recording for the reconstructed last movement alone, as a sort of curiosity. The fact that movements 1 - 3 are so well done is the icing on the cake!
